multiple checkbox values inserting using foreach loop, jquery and ajax - php

Question

I have input field checkboxes,
<input value="1" name="rubric_chkbox[]" type="checkbox" class="checkbox" />
<input value="2" name="rubric_chkbox[]" type="checkbox" class="checkbox" />
<input value="3" name="rubric_chkbox[]" type="checkbox" class="checkbox" />
My problem is that in my foreach loop insert query if I checked all the checkbox,
It will just insert value 1 and 2 in my database it ignores the value 3.
I'm using jquery and ajax to get the checkboxes.
var rubricChkbox = new Array();
$(".rubricChkbox:checked").each(function() {
rubricChkbox.push($(this).val());
});
console.log(rubricChkbox);
$.ajax({
url: "Queries/save.php",
type: "POST",
data: {
"rubricChkbox":rubricChkbox
},
success: function(yey){
console.log(yey);
alert(yey);
}
});
});
});
And this is my save.php,
if (isset($_POST['rubricChkbox']) || isset($_POST['uncheked']) || isset($_POST['user_id'])) {
$rubric_value = $_POST['rubricChkbox'];
$IDuser = $_POST['user_id'];
foreach($rubric_value as $rubric_check) {
$sql_check = "SELECT raw_selected_rubric FROM rubric_selected INNER JOIN cmat_composition ON rubric_selected.ID_cmat = cmat_composition.ID_cmat WHERE rubric_selected.ID_users = '$IDuser' AND raw_selected_rubric = '$rubric_check'
AND rubric_selected.Saved = '1'";
$result_check = mysqli_query($conn,$sql_check);
if (mysqli_num_rows($result_check) <= 0){
$sql_raw = "INSERT INTO rubric_selected (raw_selected_rubric, Saved, ID_users)
VALUES ('$rubric_check', '1', '$IDuser')";
mysqli_query($conn, $sql_raw);
}
}
What did I missed out? Thank you.

The best advice for you is that if something doesn't work the way you want, you should examine what happens at each step until you find the problem. This doesn't only apply to this question, but to any programming problem (and many others).
In this case
Is the data sent from the browser correct? You already have the statement console.log(rubricChkbox);. Did you check that value? Why didn't you include it in the the question?
Does the correct data arrive at the PHP script? Use something like print_r ($_POST);.
The SQL INSERT depends on the result of a SQL SELECT. Did you check that this condition is true, because otherwise your code wont even try to insert.
Does the INSERT statement return some error?
